Abstract: The present disclosure relates to an animal knee joint implant that reflects an anatomical structure of an animal. More particularly, the present disclosure relates to an animal knee joint implant that reflects the anatomical structure of an animal, wherein the knee joint implant is capable of being used for diseases, which are accompanied by bone loss, damage to surrounding muscles, ligaments, and the like and are thus more complex than general knee joint diseases such as rheumatoid arthritis and degenerative arthritis, and wherein the animal knee joint implant is capable of reinforcing stability against varus and valgus as well as stability against flexion and extension, and capable of easily complementing gaps that may occur when the bones of a joint are cut.

Abstract: A total ankle replacement prosthesis may comprise a tibial implant, a talar implant, and an intermediate implant. The intermediate implant may fixedly attach to the tibial implant and may articulate with respect to the talar implant. The intermediate implant may have unequal front and back angular extent, so as to discourage a particular direction of subluxation, and a kit may be provided containing various such intermediate implants. Various features may be provided in regard to dovetails, fins, recesses, the placement of fins and pegs, and the shape of the perimeter of the tibial implant. Recesses may allow a surgical blade to slice a latch off of an already-installed intermediate implant, in order to allow its removal from the tibial implant.

When implanted, the proximal region of the stent and the proximal region of the valve are aligned with a native valve, and the distal region of the valve is distally spaced-apart from the native valve.

Abstract: Devices, systems, and methods to improve both the reliability of soft tissue repair procedures and the speed at which the procedures are completed are provided. The devices and systems include one or more structured tissue augmentation constructs, which include constructs that are configured to increase a footprint across which suture applied force to tissue when the suture is tied down onto the tissue. The tissue augmentation constructs can be quickly and easily associated with the repair suture and can be useful in many different tissue repair procedures that are disclosed in the application. The present disclosure includes structured tissue augmentation blocks for tendon repair that have a flexible or semi-flexible skeleton integrated into the block. The skeleton can be bioabsorbable and can create both in-plane and out-of-plane curvature in the block.

Abstract: A joint spacer has first and second endplates, with each having a bone engaging surface, and at least two cams with an inclined cam surface positioned on an opposite side. First and second slides, each having ramps with an inclined surface are engaged with the cams of the endplate. The first slide has an angled portion at an end, and the second slide has a hinge portion. A threaded shaft has a hinge portion connected to the slide hinge portion, connecting the shaft to the slide, enabling the shaft to pivot. A nut is threaded to the shaft, and can contact and interfere with the angled portion of the first slide to drive the first slide with respect to the second slide. This results in engagement of the cams and ramps to drive the endplates apart to increase the spacer height.

Abstract: A size adjustable cover used for soft tissue reinforcement which is adapted to envelop an implantable device, such as a breast implant, in a surgical application. The cover is formed using a circular two-dimensional implantable matrix material having an inner circle and a plurality of fringes which radiate circumferentially from the inner circle. The implantable device is positioned upon the inner circle, and the plurality of fringes are folded inwardly to form an overlapping implant pocket which envelops the implantable device. Each fringe further has a punched opening, allowing a loop of suture thread to link each fringe together. Certain fringes are excluded from the loop to create stabilization tabs which radiate from the inner circle and are attached to a site of host implantation to stabilize the cover and the implantable device within.
